COTTON-GIN.

Specification of Letters Patent.

Patented Aug. 8, 1905.

A lication filed December 1, 1904. Serial No. 235,032.

To all whom it natty concern: Be it known thatI, FRANK PHELPS, acitizen of the United States, residing at VVellston, in the county of Lincoln and Territory of Oklahoma, have invented certain new and useful Improvements in Cotton-Grins; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cotton-gins and similar machines for separating cotton or the like fibrous material from its seed, hulls, or

other cellular matters associated therewith, and particularly to means employed in connection with the ginning mechanism for separating and discharging dirt, motes, brush, and other waste or foreign matter from the material.

In my pending application for patent, filed March 19, 1904. Serial No. 199,021, I have disclosed and claimed a similar invention in cotton-gins whose object is to discharge the dirt, motes, and other waste from the cotton fiber as it is drawn by the saws through the bars of the breastplate and before the material adhering to the saws reaches the brush, this being accomplished by centrifugal action due to rotation of the saws, aided by air-suction. The machine therein illustrated and described has a brush located below or lower than the saws and a waste-chamber above the brush-chamber, into which the dirt, motes, or other waste is thrown by centrifugal force from the adhering fibrous material on the saws and from which it is drawn ofl by a draft or suction, materially aiding the centrifugal ejecting action.

My present improvement applies the same general principles.

The objects are to adapt the invention more readily to the ordinary and usual forms of gins in which the brush is located approximately on a level with the saws and to simplify and improve the construction and efficiency of the cleansing apparatus.

The accompanying drawing, which forms a part of this specification, is a cross-sectional perspective view of an ordinary cotton-gin containing a preferred embodiment of my invention, which will be fully described by reference to said drawing and then particularly pointed out and defined in the following claims. I

1 indicates the roll-box; 2, the breastplate; 3, the saws; 1, the brush, and 5 the brushchamber, having its discharge-chute leading to the lint cylinder or tube 6.

Above the brush is a waste or dust chamher 7, having a contracted inlet-chute 8 projecting therefrom, curving down over the brush and having its mouth flaring or widened and open at the space between the brush and saws or behind the point where the cotton is drawn by the saws through the breastplate. This dust-chamber is in communication with any appropriate suction device. As shown, it is connected by a pipe 9 with a pneumatic conveying-tube 10, which may run the whole length of a ginnery or plant and be connected to the dust-chambers of all the gins. The connecting pipe or tube 9 is shown curved to clear the gin-feeder. having a discharge-pipe 11, connected to a blower 12.

Between the lower sideof the waste-chamber or dust-tube and the upper side of the brush-chamber is an air-passage 13, through which air entering as indicated by the arrow is supplied to the space between the brush and saws and sucked up through the mouth of the inlet-chute 8 into the dust-chamber? In operation the cotton is caught by the saws and drawn through the breastplate, thus separating the lint or fiber from its seeds, which are retained in the roll-box in the usual way, while the fiber adheres to the saw-teeth until it is removed by the brush. As the saws rotate rapidly, all wastesuch as dirt, motes, and brush-is ejected into the enlarged mouth of the chute 8 and sucked up into the dust-chamber and discharged through the tube 10, air being properly supplied through the passage 13. The contracted neck of the chute 8 causes an increased draft through this narrow space, which more effectively sucks up the dust and motes.

As stated in my former specification, it may be desirable in some cases to have the bars of the breastplate spaced sufficiently apart to permit the seeds to pass through, in which case the lint or fiber would not be separated, but the hulls, brush, and waste would be carried off by the air-current, so that this invention, like the former, is adapted for ejection of dirt and waste either before or after the ginning operation.

I claim as my invention and desire to secure by Letters Patent of the United States+ 1. In a cotton-gin or machine of similar character, the combination with the ginning mechanism, including the breastplate, saws The tube 10 is shownand brush behind the saws, of the dust-chaman air-passage between the brush-chamber and brush behind the saws, of a dust-chamber above the brush having an inlet-chute curving down over the brush and having its mouth opening in the space between the brush and saws, and means for creating air-suction in said dust-chamber.

2. In a cotton-gin or machine of similar character, the combination with the ginning mechanism, including the breastplate, saws ber above the brush-chamber having an inletchute whose mouth is disposed to receive motes and waste ejected by centrifugal force from the fiber adhering to the rotating saws,

and dust-chamber for supplying air to the mouth of said inlet-chute, and means for creatmg a suction-draft in said dust-chamber. 1

3. In a cotton-gin or machine of similar character, the combination with the ginning mechanism, including the breastplate, saws, and means for removing the adhering lint or fibrous material from the saws, of a dustchamber having a contracted inlet-chute with a wider or flaring mouth disposed to receive motes, dust or waste ejected by centrifugal action from the saws, and means for creating suction in said dust-chamber, the draft being relatively increased through the inlet-chute by reason of its contracted form.

In testimony whereof I afiix my signature in presence of two witnesses.

FRANK PHELPS.
